Researchers have developed a “bioengineered skin so tough
that it stops a speeding bullet from penetrating.” In the first segment,
the bullet is moving at half speed; “repeated with a round moving at a
full 1,080 feet per second, the skin gives way.” But both half-speed and
full-speed tests were also conducted with real human skin and human
skin augmented with regular silkworm silk, as well as with piglet skin.
In all cases, the bullet won out. The only exception was the
bioengineered spider silk tissue.
